Ben Stiller and Naomi Watts are Josh and Cornelia Srebnick, happily married middle-aged members of New York’s creative class. They tried to start a family and were unable to — and have decided they’re okay with that. But as Josh labors over the umpteenth edit of his cerebral new film it’s clear that something is missing.

Enter Jamie (Adam Driver) and Darby (Amanda Seyfried), a free-spirited young couple, who are ready to drop everything in pursuit of their next passion — retro board games one day, acquiring a pet chicken the next. For Josh, it’s as if a door has opened back to his youth.

It’s not long before the restless forty-somethings, Josh and Cornelia, throw aside friends their own age — including Beastie Boy Adam Horovitz in a sly supporting role — to trail after these young hipsters who seem so plugged in and uninhibited.

While We’re Young is an openly funny cross-generational comedy of manners about aging, ambition and success, as well as a moving portrait of a marriage tested by the invading forces of youth. No film has better captured the weird, upended logic of urban sophisticates: the older ones embracing their iPads and Netflix, the young ones craving vinyl records and vintage VHS tapes.

Powered by Stiller and Driver’s note-perfect lead performances and loose, comic turns by Watts and Seyfried, WHILE WE'RE YOUNG is an absolute delight.
